Original patch (taken from GCC 12 branch version) edited for GCC 8 to
use .c rather than .cc filenames and to update aarch64.c changes to
apply to GCC 8.
commit 587b370c8492aadaab14c57e242c66778cc78891
Author: Richard Sandiford <richard.sandiford@arm.com>
Date: Tue Mar 11 15:51:55 2025 +0000
Fix folding of BIT_NOT_EXPR for POLY_INT_CST [PR118976]
There was an embarrassing typo in the folding of BIT_NOT_EXPR for
POLY_INT_CSTs: it used - rather than ~ on the poly_int. Not sure
how that happened, but it might have been due to the way that
~x is implemented as -1 - x internally.
gcc/
PR tree-optimization/118976
* fold-const.cc (const_unop): Use ~ rather than - for BIT_NOT_EXPR.
* config/aarch64/aarch64.cc (aarch64_test_sve_folding): New function.
(aarch64_run_selftests): Run it.
